DNA Adductomic Analysis by Data-Independent Mass Spectrometry

A new type of analysis called "wide-selected ion monitoring (SIM)/MS²" scanning, is capable of screening for a wide range of DNA adducts (chemical modifications to genomic DNA). This method has successfully identified DNA adducts from carcinogen exposures and oxidative stress in human prostate and kidney tissues. read more

Targeted Metabolomics Analysis of Type 2 Diabetes Serum Samples Using Mass Spectrometry and a Standardized Quantitative Method

An important advantage of standardized methods is that they enable comparability between laboratories and across studies. In this work, the author used a standardized targeted kit to demonstrate the accuracy, sensitivity, and reproducibility of the approach, analyzing serum samples obtained from type 2 diabetes study subjects and healthy controls. read more

High-Throughput Analysis of Volatile Compounds in Air, Water, and Soil Using SIFT-MS

For the BTEX compounds, detection limits in the single-digit parts-per-billion concentration range (by volume) are readily achievable within seconds using selected ion flow tube mass spectrometry (SIFT-MS), because sample analysis is achieved without chromatography, preconcentration, or drying. read more
